Abstract: The cleaning device (2) comprises a vat (3) closed by a cover (4) provided with a water inlet and water outlet. Inner volume of the vat defines a housing arranged to hold a unit for filtering the water and/or water treatment unit. The vat comprises a unit for recovering solid particles obtained from the treatment and/or filtration of water. The housing, water filtration unit and water treatment unit are arranged such that the vat is equipped with the water filtration unit and/or water treatment unit according to the freely interchangeable arrangements chosen by the user. The cleaning device (2) comprises a vat (3) closed by a cover (4) provided with a water inlet and water outlet. Inner volume of the vat defines a housing arranged to hold a unit for filtering the water and/or water treatment unit. The vat comprises a unit for recovering solid particles obtained from the treatment and/or filtration of water. The housing, water filtration unit and water treatment unit are arranged such that the vat is equipped with the water filtration unit and/or water treatment unit according to the freely interchangeable arrangements chosen by the user. The housing comprises a symmetrical structure with respect to a vertical plane. The water filtering unit and the water treatment unit are contained in specific compartments arranged to be laid in the housing. The compartments define two interchangeable and replaceable water filtration cartridges (6). The water filtration cartridge comprises a basket of parallelepiped form closed by a hood and the walls and the bottom are perforated. The basket is provided with a unit for selecting the direction of water flow through the filtration unit contained in the basket. The unit for selecting the direction of water flow comprises guides provided with a row of openings, where each guide is sliding and mounted on a side face of the hood to be movable between a first position in which the row of openings coincides with a row of openings distributed over the side face of the hood to allow the passage of water through the openings and a second position in which the row of openings is spaced with respect to the row of openings to stop the passage of water through the openings. The water filtering cartridge comprises a unit for cleaning the water filtration unit. The cleaning unit comprises a perforated tube extending within the basket and provided with a connector arranged to be connected to an inlet of clean water. The perforated tube comprises a section of variable size selected according to volume function of the water filtering unit to be cleaned. The water filtering cartridge comprises a unit for aerating the water filtration unit. The aeration unit comprises a pipe extending within the basket and provided with a connector arranged to be connected to external air inlet. The water treatment cartridge (7) comprises a box of shape and size identical to those of the water filter cartridge inside of which an ultraviolet radiation lamp is extended. The box comprises a perforated bottom for the inlet of water and an opening for the water outlet located near the upper end of one of its lateral faces. The box comprises a deflector located near the perforated bottom in the extension of one of its side faces and arranged to force the flow of water passing the vat towards the perforated bottom. The bottom of vat is inclined with respect to a horizontal plane, and comprises a settling basin for solid particles connecting with the housing. The housing and the settling basin are separated by a wall arranged to allow the passage of water from the housing towards the settling basin and stop the passage of water of the settling basin towards the housing. The wall comprises a blocking unit for maintaining the vat in a position in which its lower end stops above the bottom the vat at a distance such that a passage is provided for the water arriving from the housing. The settling basin comprises a removable receptacle for evacuation of solid particles without loss of water in the basin. The assembling unit is arranged to assemble the legs of two adjacent vats and water inlet opening (8) of the vat with the opening of the water outlet of the adjacent vat. An INDEPENDENT CLAIM is included for a cartridge disposed in a housing of water cleaning device.
